Depending upon the design of the system, pneumatic
cylinders can operate in a variety of ways. Examples
include having the ability to perform multiple strokes
without the need for intermediate intervention, to perform
a full stroke with intermediate stopping points, to be
adjusted so as to control the amount of extension and/or
retraction of the piston rod once actuated.

Pneumatic cylinders will vary in appearance, size and
function, there are also numerous other types of pneumatic
cylinder available, many of which are designed to fulfill
specific and specialised functions.
